## Is an AND gate a transistor?

From Transistors to Functions. For the purpose of this class, we will consider transistors to be the basic building blocks of computer hardware. A transistor is an electronic device that has three ends: a source, a sink, and a gate.

## How many transistors are in a XOR gate?

XOR gate in CMOS can be implemented using minimum of 8 transistors. 2:1 MUX implementation.

## How many transistors are there in 3 inputs NAND gate?

6 transistors
An alternative design for the 3-input NAND gate uses CMOS transistors as building blocks, as shown in Figure 4.2. This circuit needs only 6 transistors, and is symmetric w.r.t. its inputs.

## How many inputs are there in an AND gate?

The AND Gate If any input(s) is “low” (0), the output is guaranteed to be in a “low” state as well. In case you might have been wondering, AND gates are made with more than three inputs, but this is less common than the simple two-input variety.

## How many and gates are required for a 8 to 1 multiplexer?

From the above Boolean equation, the logic circuit diagram of an 8-to-1 multiplexer can be implemented by using 8 AND gates, 1 OR gate and 7 NOT gates as shown in below figure.

## What is the symbol of XOR gate?

An XOR gate is also called exclusive OR gate or EXOR. In a two-input XOR gate, the output is high or true when two inputs are different. In Boolean expression, the term XOR is represented by the symbol (⊕) and the Boolean expression is represented as Y = A ⊕ B.

## Which logic family is fastest?

Emitter-coupled logic
Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as the fastest logic available. ECL achieves its high-speed operation by employing a relatively small voltage swing and preventing the transistors from entering the saturation region.

## Can we convert or gate to gate?

It is still possible to create an OR function from an AND / NAND gate and inverters, or an AND gate from a NOR / OR function. The diagram below gives some of the conversions. As an example it can be seen that a NOR gate is the same as an AND gate with two inverters on the input.

## Can an AND gate have 3 inputs?

Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.

## How many transistors are there in a NAND gate?

A NOT gate is 1 transistor. A NAND gate is 1 transistor per input. A NOR gate is 1 transistor per input. An AND gate is basically a NAND gate + a NOT gate, so it takes 1 transistor more than a NAND gate. Same for OR vs NOR.
